AIR BAG INDICATOR LIGHT CAME ON IN MID JANUARY 2008 AND HAS REMAINED ON. THE CAR JUST WENT OUT OF WARRANTY IN AUG 2007. SINCE I HAVE BEEN DEPLOYED FOR 15 MONTHS, I WAS NOT ABLE TO DISCOVER THIS PROBLEM WHILE IT WAS STILL UNDER STANDARD WARRANTY. AFTER CONTACTING CHEVROLET ABOUT SEVERAL ISSUES WITH THE BRAKES AND AIR BAG LIGHT, THEY INSTRUCTED ME TO GET IT DIAGNOSED. THE DIAGNOSIS REVEALED AN ECW FAILURE BUT NOTHING COULD BE FOUND WRONG WITH THE BRAKES. RECOMMENDATION FROM CHEVROLET SERVCO IS TO HAVE ECW FIXED. AFTER THE OCCURRENCE WITH THE BRAKES, MY HUSBAND BEGAN DRIVING THE VEHICLE. *TR

REAR BRAKES LOCKED ON APPLICATION, LUCKILY RIGHT IN MY DRIVEWAY. RELEASED BY ROCKING BACK AND FORTH, ONLY TO LOCK AGAIN....PULLED DRUMS MYSELF TO FIND ALL FOUR LININGS DELAMINATED FROM SHOES! PHONED GM CANADA AND GOT ABSOLUTELY NOWHERE UNTIL I MENTIONED THE FACT THAT I CAREFULLY TOOK PICTURES AND IT WAS LUCKY THAT NO ONE WAS KILLED! HAVING A SUDDEN CHANGE OF HEART, THEY PHONED MY DEALERSHIP AND ARRANGED FOR A FREE SET OF SHOES, WHICH I INSTALLED, SINCE I LIVE THREE HOURS FROM A DEALERSHIP. I'M SATISFIED WITH THE PROCESS, EXCEPT FOR THE FACT THAT THIS COULD CONCEIVABLY HAPPEN TO ANY AVEO AT ANY TIME! MINE HAD 70000 KMS. (45,000 MILES) ON IT AT THE TIME, 85% LININGS! HAVE YOURS CHECKED!! NO DUST IN THE DRUMS, EITHER. SCARY!! *TR

I PURCHASED MY 04 CHEVY AVEO ON JUNE 20,06. FIVE DAYS LATER THE BRAKES WERE METAL TO METAL. MY CAR WAS NOT SAFETY INSPECTED BEFORE THE SALE. SINCE THEN I HAVE TAKEN THE CAR BACK TO WHERE I PURCHASED IT SEVERAL TIMES AND HAVE EVEN HAD THE SERVICE MANAGER TO RIDE WITH ME TO SHOW HIM THAT THE BRAKES ARE STICKING. (THE CALIPERS NEED TO BE REPLACED) TIM MARBURGER CHRYSLER/DODGE TRIED TO SAY THAT IS WAS A WARPED ROTOR DUE TO EXCESSIVE MOUNTAIN DRIVING, MY CAR WAS ONLY DRIVEN 7 MILES ONE WAY TO GO CAMPING AND 7 MILES BACK ONCE A WEEK. I WOULD HARDLY CALL THIS EXCESSIVE. THE FIRST TANK OF GAS I GOT THE MILEAGE OF 284 MILES SINCE 06/20/06 UNTIL NOW 10/10/06 MY GAS MILEAGE FOR A TANK OF GAS IS NOW 210 MILES. NOBODY AT THE DEALERSHIP HAS OFFERED TO FIX MY CAR. I HAVE BEEN CUSSED, TALKED TO LIKE A DOG. THE GENERAL MANAGER DENNY FRUITH SLAMMED MY CAR DOOR AND PROCEEDED TO ARGUE WITH ME IN THE FRONT PARKING LOT IN FRONT OF THE SHOWROOM DOORS. REFUSED TO FIX MY CAR AND IT WAS STILL UNDER WARRANTY, THE DEALERSHIP PUT MY LUG NUTS ON SO TIGHT THAT THEY COULD NOT BE MANUALLY TAKEN OFF. THE VICE PRESIDENT OF THE COMPANY MR. FELIX MCCLAT REFUSED TO FIX MY BRAKES AND ALSO REFUSED TO EVEN LET ME COME TO THE DEALERSHIP AND HAVE THEM LOOSEN MY LUG NUTS. AND THE CAR WAS STILL UNDER WARRANTY. THE BRAKES ON MY CAR WILL PUT THEMSELVES ON WITHOUT ME PRESSING THE PEDALS. AND WHEN YOU DO PRESS THE PEDALS YOU CAN BE GOING DOWN HILL AND TAKE YOUR FOOT OFF THE PEDAL AND THE BRAKES GRAB AND THE CAR WILL COME TO ALMOST A COMPLETE STOP...DOWN HILL. ALL THIS WAS SHOWN TO THE SERVICE MANAGER DAVID ANDERSON AND THE CAR HAS NOT BEEN FIXED YET. *JB

FILL UP ON WED OF ONE WEEK, USE ONLY 34 MILES, MUST FILL UP BY TUESDAY OF NEXT WEEK, THE BRAKES MAKE LOUD NOISE LIKE BRAKES ARE GOING OUT, MORE OF STEEL RUBBING, PULLS EXCESSIVELY TO THE RIGHT. TOOK VEHICLE IN FOR REPAIR ON THE BRAKES, WAS TOLD DUST WAS ON THE ROTORS, CLEANED OUT, PROBLEM STILL EXIST, NOW A BUCKLING IS FELT WHEN BRAKES ARE APPLIED. AS FOR THE GAS PROBLEM, CAR WAS LEFT OVERNIGHT, I TOLD THE DEALERSHIP, I DO NOT WANT MY CAR BACK UNTIL THEY FIND THE PROBLEM.. CHECK THE FUEL INJECTORS, THE GAS TANK, CHECK THE FUEL PUMP, CHECK ALL THE COMPONENTS OF THE GAS LINE.. I DO NOT SMELL GAS, THERE IS NO GAS ON THE GROUND. I HAVE A LOANER CAR FOR NOW. AS FOR THE SES LIGHT, I SHOULD DESCRIBE WHAT THE PROBLEM IS SO THAT THE DEALERSHIP SERVICE DEPT CAN GO STRAIGHT TO THE PROBLEM. THE CAR PULL EXCESSIVELY TO THE RIGHT AND LEFT, THIS TOO WILL BE CHECKED OUT BY THE DEALERSHIP. NO UPDATE RESOLUTION SO FAR. WILL KEEP YOU POSTED. THE CLOCK MALFUNCTIONED.
